Facile Oxidative Rearrangements Using Hypervalent Iodine Reagents
Aromatic substituents migrate in a novel oxidative cyclization mediated by iodine(III) reagents. 4-Arylbut-3-enoic acids are cyclized and rearranged to 4-arylfuran-2(5H)-ones by hypervalent iodine compounds in good to excellent yields under mild reaction conditions. Other ring sizes are also accessible. The mechanism of the reaction is described in detail, and calculations highlight the cationi...
متن کاملEnantioselective Oxidative Rearrangements with Chiral Hypervalent Iodine Reagents
A stereoselective hypervalent iodine-promoted oxidative rearrangement of 1,1-disubstituted alkenes has been developed. This practically simple protocol provides access to enantioenriched α-arylated ketones without the use of transition metals from readily accessible alkenes.
متن کاملAsymmetric Synthesis with Hypervalent Iodine Reagents.
This chapter describes recent developments in stereoselective synthesis using hypervalent iodine reagents.
متن کاملStereoselective Ketone Rearrangements with Hypervalent Iodine Reagents.
The first stereoselective version of an iodine(III)-mediated rearrangement of arylketones in the presence of orthoesters is described. The reaction products, α-arylated esters, are very useful intermediates in the synthesis of bioactive compounds such as ibuprofen. With chiral lactic acid-based iodine(III) reagents product selectivities of up to 73 % ee have been achieved.
متن کاملThioamination of Alkenes with Hypervalent Iodine Reagents
An efficient thioamination of alkenes mediated by iodine(III) reagents is described. The use of different sulfur nucleophiles allows the flexible synthesis of 1,2-aminothiols from alkenes. By employing chiral iodine(III) reagents, a stereoselective version of the thioamination protocol has also been developed.
